What is the 2006-2011 Honda Civic Timing Chain VTC Actuator Rattle on Cold Start (8th Gen)?
The 8th generation Civic (2006-2011) equipped with the R18A and K20Z3 engines suffers from Variable Timing Control (VTC) actuator failure causing a loud metallic rattling noise on cold startup that typically lasts 1-5 seconds before oil pressure builds. The actuator locks the cam… Repairs typically run $350-$800. Severity: high.
What is the 2001-2011 Honda Civic Radiator Internal Transmission-Cooler Failure — ATF/Coolant Cross-Contamination ('Strawberry Milkshake')?
On automatic-transmission Civics the ATF cooler is integrated inside the radiator's end tank. As the radiator ages the internal cooler wall corrodes/breaches, letting engine coolant and transmission fluid mix. The result is a pink, milky emulsion (a 'strawberry milkshake') visibl… Repairs typically run $400-$3,500. Severity: high.
What is the 2006-2009 Honda Civic 8th-Gen 1.8L Cracked Engine Block — Coolant Leak and Overheating (R18 Casting Defect)?
A casting/manufacturing defect in the R18 1.8L engine block causes the cylinder block to crack — typically on the back of the block beneath the oil/air separator, in the PCV-system area. The crack lets coolant slowly seep out (and into the PCV system), so the car loses coolant wi… Repairs typically run $1,000-$6,000. Severity: high.
What is the 2006-2011 Honda Civic Rear Subframe / Trailing-Arm Corrosion in Salt-Belt Regions (8th Gen)?
In road-salt states, high-mileage 8th-gen Civics develop significant corrosion of the rear subframe and rear trailing-arm/axle mounting areas. Salt-laden moisture collects in the boxed sections and rusts them from the inside out, leading to flaking scale, perforation, clunking ov… Repairs typically run $300-$2,000. Severity: high.
What is the 2006-2015 Honda Civic Sunroof Drain Tube Clogging Causing Interior Water Damage?
Civic models with factory sunroofs (EX and above) experience clogged sunroof drain tubes leading to water intrusion into the cabin. The four drain tubes (front left/right, rear left/right) collect debris and become pinched, clogged, or disconnected from the body grommets. Water a… Repairs typically run $0-$1,200. Severity: medium.
What is the 2001-2020 Honda Civic P0741 — Torque Converter Clutch Stuck Off from a Failing TCC Lock-Up Solenoid / Worn Converter?
P0741 sets when the PCM commands the torque converter clutch (TCC) to lock up but the measured engine-vs-input RPM slip (greater than ~200 RPM) shows it is not engaging (stuck off) or slipping. It applies only to automatic/CVT-transmission Civics. This is a well-known Honda autom… Repairs typically run $150-$2,500. Severity: medium.
What is the 2001-2011 Honda Civic SRS Clockspring / Cable-Reel Failure — Airbag Light, Dead Horn and Cruise?
The clockspring (cable reel) is the coiled ribbon conductor in the steering column that keeps the driver airbag, horn, cruise and steering-wheel controls connected while the wheel turns. Its fine wires fatigue and break, setting a latching SRS code (Honda 10-2, driver's airbag) t… Repairs typically run $100-$350. Severity: medium.
What is the 2006-2011 Honda Civic Si 6-Speed 3rd-Gear Grind and Gear Pop-Out — Worn Synchros (8th-Gen K20)?
The 8th-gen Civic Si 6-speed manual is known for a notchy/grinding 3rd gear and for popping out of 2nd, 4th and 6th. The grind into 3rd is worst when the gearbox oil is cold or in the morning and is caused by the 3rd-gear synchro (and carbon double-cone synchros) wearing prematur… Repairs typically run $600-$2,500. Severity: medium.
What is the 2006-2011 Honda Civic Passenger-Side Hydraulic Engine Mount Failure — Heavy Idle Vibration (8th Gen)?
The 8th-gen Civic uses a fluid-filled hydraulic engine mount on the passenger side (P/N 50820-SNA-P01). Its rubber diaphragm ruptures and the mount loses its damping fluid, so engine vibration transmits directly into the chassis. Owners feel strong shaking at idle (worst in Drive… Repairs typically run $150-$450. Severity: medium.
What is the 2006-2022 Honda Civic P0442 — Small EVAP Leak from a Degraded Gas Cap Seal or Cracked Vapor Hose?
P0442 sets when the Civic's PCM runs its EVAP self-test and detects a small leak (roughly 0.020-0.040 in). On the Civic the overwhelmingly most common source is the fuel-filler cap: the rubber O-ring on the cap hardens and shrinks with age/heat and stops sealing, which is why a P… Repairs typically run $20-$300. Severity: low.
What is the 2006-2024 Honda Civic P0455 — Gross EVAP Leak from a Failed Gas Cap or Stuck-Open Purge/Vent Valve?
P0455 indicates a large (gross) leak in the evaporative emission system — the PCM cannot build or hold EVAP vacuum/pressure at all. On the Honda Civic the two most frequent causes are strikingly simple: a gas cap that no longer seals (missing, loose, or a badly degraded O-ring) a… Repairs typically run $30-$350. Severity: low.
What is the 2001-2011 Honda Civic Valve Cover Gasket Oil Leak — Burning Smell and Oil in Spark-Plug Wells?
The valve cover gasket (and the round spark-plug tube seals) harden and shrink with age on D17 and R18 engines, letting oil weep onto the block and exhaust manifold. Oil dripping onto the hot manifold produces a burning-oil smell and light smoke; oil pooling in the spark-plug wel… Repairs typically run $90-$350. Severity: low.
What is the 2001-2011 Honda Civic Power Window Regulator and Motor Failure?
The plastic sliders, cable/track and motor of the power window regulators wear out, most often on the driver's door which sees the most cycles. The window slows, moves unevenly, binds off-track, or drops into the door and won't come back up. It is a high-volume search item on bot… Repairs typically run $90-$350. Severity: low.
